RESUMO
Purpose: To determine the level of awareness and knowledge about glaucoma surgery and post-surgery counseling amongst paramedical staff at a tertiary eye-care hospital. Methods: This observational cross-sectional study included a random sample of 94 hospital personnel: 37 general nurse midwives, 47 ophthalmic assistants, and 10 patient caretakers (PCTs). Participants were administered a questionnaire about glaucoma surgery and post-surgery counseling of patients. Results: The study included 41 (43.6%) females and 53 (56.4%) males. The mean age of the participants was 24.85 ± 4.54 years. All participants were aware of trabeculectomy surgery in glaucoma (100%). A total of 95.7% knew that surgery helps in controlling IOP, of whom 57 (60.6%) participants got information during their course of learning. Overall 53 (56.4%) believed that surgery is done when medication failure occurs, and 58 (61.7%) knew that surgery helps in preserving vision. A total of 63 (67.0%) participants knew to counsel patients to visit an ophthalmologist when called for and take the treatment as advised, whereas 74 (78.7%) correctly said to visit an ophthalmologist immediately if pain/diminution of vision/discharge occurs. Overall, PCTs were found to be having significantly better knowledge (P = 0.01) compared to others and they also reported ophthalmologists as the chief source of information. Conclusion: This study revealed that paramedical staff had an excellent awareness of trabeculectomy surgery. However, the knowledge and counseling parts of the questionnaire revealed less than satisfactory responses. So, there is a need to continuously educate paramedical staff members so that they can help in propagating information about the role of glaucoma surgery and the importance of proper follow-up.

Purpose: To evaluate the gonioscopic changes in patients receiving Descemet's stripping endothelial keratoplasty (DSEK) without pre-existing ocular hypertension (OHT) and to report its correlation with post-surgery OHT, graft survival, and visual outcomes. Methods: Adult patients who underwent DSEK surgery from April 2014 to March 2018 with at least 2 years of follow-up were analyzed in this retrospective study. Demographic details, indication of DSEK, necessary anterior and posterior segment findings, and the post-DSEK OHT details were documented. Results: A total of 58 patients (23 males and 35 females) with a mean age of 61.44 ± 8.8 years were included in the study. The most common etiology for DSEK surgery was pseudophakic bullous keratopathy in 47 eyes (81.03%). A total of 22.41% (13/58) eyes showed elevated intra-ocular pressure (IOP) following DSEK surgery. The most common cause of IOP elevation was steroid-induced OHT in seven eyes (12.06%). Gonioscopy examination revealed areas of peripheral anterior synechiae (PAS) in 17 (29.3%) eyes. OHT was found in 4/17 (23.5%) eyes having PAS. Three of these cases required trabeculectomy + goniosynechiolysis (GSL), and the fourth case required GSL alone to control IOP. These four cases also required repeat DSEK for failed grafts. The mean pre-operative best corrected visual acuity was 1.62 logMAR (range 1.17-1.77), which gradually improved to 0.79 logMAR (range 0.3-1.77) after 2 years (p < 0.00001). Conclusion: PAS was found to be an important factor associated with post-DSEK ocular hypertension in our study. OHT in PAS cases required definitive surgical treatments to control IOP. It adversely affected the graft survival and in turn affected visual outcomes also.

OBJECTIVE: To evaluate nephroprotective potential of Solanum xanthocarpum (S. xanthocarpum) fruit extract(SXE) against gentamicin (GM) induced nephrotoxicity and renal dysfunction. METHODS: Twenty-four Wistar rats were divided into four groups (n=6). Control rats that received normal saline (i.p.) and 0.5% carboxymethyl cellulose (p.o.) per day for 8 d. Nephrotoxicity was induced in rats by intraperitoneal administration of GM (100 mg/kg/d for 8 d) and were treated with SXE (200 and 400 mg/kg/d (p.o.) for 8 d). Plasma and urine urea and creatinine, kidney weight, urine output, blood urea nitrogen, renal enzymatic and non-enzymatic antioxidants and lipid peroxidation was evaluated along with histopathological investigation in various experimental groups of rats. RESULTS: It was observed that the GM treatment induced significant elevation (P<0.001) in plasma and urine urea, creatinine, kidney weight, blood urea nitrogen, renal lipid peroxidation along with significant decrement (P<0.001) in urine output, renal enzymatic and non-enzymatic antioxidants. SXE 200 and 400 mg/kg treatment to GM treated rats recorded significant decrement (up to P<0.001) in plasma and urine urea and creatinine, renal lipid peroxidation along with significant increment (up to P<0.001) in renal enzymatic and non-enzymatic antioxidants. Histological observations of kidney tissues too correlated with the biochemical observations. CONCLUSIONS: These finding powerfully supports that S. xanthocarpum fruit extract acts in the kidney as a potent scavenger of free radicals to prevent the toxic effects of GM both in the biochemical and histopathological parameters and thus validates its ethnomedicinal use.

Historical studies of Rasa shastra reveal the use of metals and minerals, both for alchemical and therapeutical purposes in ancient past. But, gradually the alchemical use of the subject, declines and the therapeutical use takes over. Rasamritam is the latest doctrine in the field of Rasa shastra which compiles the extract of the older books and adopted some new and contemporary concepts. The practical aspects of this text influence both the academicians as well as physicians in large extent. Keeping the wealthier, timely concept of this text in mind, we are trying to review and analyze it critically for the benefit of researchers and practitioners and hope the idea will be fruitful.
RESUMO
OBJECTIVE: To assess the hepatoprotective effect of Solanum xanthocarpum (S. xanthocarpum) fruit extract against antitubercular drug-induced liver toxicity in experimental animals. METHODS: Ethanolic (50%) fruit extract of S. xanthocarpum (100, 200 and 400 mg/kg bw) was administered daily for 35 days in experimental animals. Liver toxicity was induced by combination of three antitubercular drugs [isoniazid (I) 7.5 mg/kg, rifampicin (R) 10 mg/kg and pyrazinamide (P) 35 mg/kg] given orally as suspension for 35 days in rats. The hepatoprotective activity was assessed using various biochemical parameters like aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatise (ALP), total bilirubin (TBL), albumin (ALB), total protein (TP), lactate dehydroginase (LDH), and serum cholesterol (CHL). Meanwhile, in vivo antioxidant activities as lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) were measured in rat liver homogenate. The biochemical observations were supplemented by histopathological examination. RESULTS: The results demonstrated that treatment with S. xanthocarpum significantly (P<0.05-P<0.001) and dose-dependently prevented drug induced increase in serum levels of hepatic enzymes. Furthermore, S. xanthocarpum significantly (up to P<0.001) reduced the LPO in the liver tissue and restored activities of defence antioxidant enzymes GSH, SOD and CAT towards normal levels. Histopathology of the liver tissue showed that S. xanthocarpum attenuated the hepatocellular necrosis and led to reduction in inflammatory cells infiltration. CONCLUSIONS: The results of this study strongly indicate the protective effect of S. xanthocarpum against liver injury which may be attributed to its hepatoprotective activity, and thereby scientifically support its traditional use.

OBJECTIVE: To investigate the hepatoprotective potential of Solanum xanthocarpum (Solanaceae) (S. xanthocarpum) in experimental rats to validate its traditional claim. METHODS: 50% ethanolic fruit extract of S. xanthocarpum (SXE, 100, 200 or 400 mg/kg body weight) was administered daily for 14 days in experimental animals. Liver injury was induced chemically, by CCl(4) administration (1 mL/kg i. p.). The hepatoprotective activity was assessed using various biochemical parameters like aspartate aminotransferase (AST), alanine aminotransferase (ALT), Serum alkaline phosphatise (SALP) and total bilirubin. Meanwhile, in vivo antioxidant activities as lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) were screened along with histopathological studies. RESULTS: Obtained results demonstrated that the treatment with SXE significantly (P<0.05-<0.001) and dose-dependently prevented chemically induced increase in serum levels of hepatic enzymes. Furthermore, SXE significantly (up to P<0.001) reduced the lipid peroxidation in the liver tissue and restored activities of defence antioxidant enzymes GSH, SOD and catalase towards normal levels. Histopathology of the liver tissue showed that SXE attenuated the hepatocellular necrosis and led to reduction of inflammatory cells inflltration. CONCLUSIONS: The results of this study strongly indicate the protective effect of SXE against acute liver injury which may be attributed to its hepatoprotective activity, and there by scientifically support its traditional use.

Major depression is an illness with objective physical signs occurring with some consistency. These signs are retardation of movements and diminished gestures and expressions. The patient may appear tired, self-concerned, bored, and inattentive and display a loss of interest in the surroundings. Anxiety is a conspicuous and an integral element of affective state and may be expressed by severe restlessness and agitation. Muscle tension, wringing of hands, weeping and moaning, repeating over and over in a monotonous and stereotyped way phrases expressive of misery are all important clinical signs of major depression. Similarly tachycardia, dry tongue/mouth, sweaty palms and/or bodily extremities, cold clammy skin, pallor, pupillary dilatation, tremor, and the fluctuations in blood pressure with wide pulse pressure are all important and give away the underlying distress. These signs have formed an integral part of both the Hamilton Depression Rating Scale and the Montgomery-Asberg Depression Rating Scale as they have a positive correlation with the diagnosis and the severity of illness. Current practice of operational criteria does not help exclude patients with subjective perception of distress and also fails to make room for aetiopathogenesis. The DSM-IV does not include these physical signs as an integral part of the clinical picture of depression, consequently leaving the diagnosis of MDE to subjective criteria and perceptions. This could also explain a large placebo response in recent randomised controlled clinical trials.

OBJECTIVE: To investigate the possibility of glomerular retrieval from formalin left in biopsy vials and to evaluate its diagnostic value and accuracy. STUDY DESIGN: Cell blocks were prepared from 94 consecutive formalin vials left after processing of renal biopsies from 93 patients, including 25 transplant patients. The prepared cell blocks were processed with routine biopsies and evaluated separately, and the results compared. RESULTS: Of the 94 samples, 29 (23 nontransplant patients and 6 allograft recipients) showed the presence of glomeruli in cell blocks, with an average of 1.7 glomeruli per cell block. In nonallograft native renal biopsies, the histologic diagnosis of glomerular morphology in cell blocks correlated with routine biopsy in 18 of 22 cases. The least retrieval was seen in crescentic glomerulonephritis, diabetic glomerulosclerosis and diffuse global glomerulosclerosis, possibly due either to the tight adherence of the glomerular tuft to the crescent or to fibrosis. All 6 samples from transplant recipients showed normal glomeruli in routine histology and in cell block preparations. CONCLUSION: Cell blocks from discarded formalin may be a useful adjunct to routine histopathology for the diagnosis of glomerular disease in centers where inadequacy of renal biopsy is frequently reported.

BACKGROUND: Secondary biliary cirrhosis is a potential complication of post-cholecystectomy bile duct stricture (PCBDS). This study addresses the factors that determine the severity of pathological changes on liver biopsy and the correlation with long-term outcome following repair. METHODS: Liver biopsies obtained at surgery for repair of PCBDS in 71 patients were reviewed and pathological changes were scored from 0 to 3. Patients with fibrosis score 0-2 were categorized as the non-cirrhotic group and those with score 3 (secondary biliary cirrhosis) were categorized as the cirrhotic group. Clinical and biochemical parameters, stricture type and outcome were analyzed by univariate and multivariate analysis for correlation with degree of fibrosis. Follow-up liver biopsies (3-60 months) after stricture repair were obtained in five patients. RESULTS: There were 58 patients in the non-cirrhotic group and 13 in the cirrhotic group. On univariate analysis, portal hypertension and prolonged injury-repair duration correlated with secondary biliary cirrhosis. Patients with a fair outcome in the cirrhotic group (4/13) had derangements in liver function tests but had patent biliary enteric anastomosis on evaluation. Of the five patients in whom liver biopsies were obtained at follow up, two had regression, two were static, and one had progression. CONCLUSION: All patients with PCBDS had varying degrees of fibrosis. Prolonged injury-repair interval and portal hypertension were the important parameters correlating with secondary biliary cirrhosis. Early repair of biliary stricture is recommended to prevent liver fibrosis. A successful relief of biliary obstruction may halt and/or reverse pathological changes in the liver.

This study was conducted to (1) see the histopathological distribution of different subtypes in steroid resistant nephrotic syndrome (SRNS) and (2) compare the clinical, biochemical parameters and outcome between Minimal Change Disease (MCD) with non-MCD subtypes in response to immunosuppressive therapy. A retrospective analysis was done of data on all biopsy proven children with idiopathic SRNS (no response to 4 weeks of standard prednisone therapy (60 mg/m(2)/day)) referred to our institute over last 12 years. They were treated with one of the following medications: oral or intravenous cyclophosphamide, cyclosporine or combination of dexamethasone and azathioprine. A comparison was done of the demographic clinical and biochemical features different histopathologies. We studied 136 children with SRNS (100 M, 36 F). They accounted for 15.1%(136/900) of all children with idiopathic nephrotic syndrome. Focal segmental glomerulosclerosis (FSGS) was the commonest 80/136 (59%), followed by MCD (17.6%). Children with non-MCD had a significantly greater prevalence of microhematuria as compared to MCD. The other baseline clinical and biochemical features including the glomerular filtration rate (GFR) were similar. After a mean follow up of 46 (8-148) months, a significantly greater children with non-MCD 65/112) continued to be proteinuric as compared to the MCD (3/24) (p=0.0001). FSGS was the commonest cause of SRNS in our patient population. Children with SRNS secondary to MCD are more likely to achieve remission as compared to non-MCD subtypes and have a better long-term prognosis. Hence kidney biopsy is of significant prognostic value in SRNS.

This paper examines the role of selective serotonin reuptake inhibitors (SSRIs) in the treatment of hepatitis-C virus (HCV) patients who have developed interferon-alpha induced depression. A 2-year data analysis of HCV psychiatric liaison clinic has been undertaken. The diagnosis, treatment, and progress of those patients who were treated with interferon-alpha (INF-alpha) are reported. 53 of the 78 patients enrolled at the HCV Clinic and treated with INF-alpha were referred for psychiatric consultation. Six patients developed major depressive illness following INF therapy. They were all treated with SSRIs and they made full recovery. This is a significant observation and is concordant with other studies. Its biochemical ramifications are presented. It is concluded that INF-induced depression is fully reversible. A hypothesis is proposed that SSRIs modulate the neuro-protective neurotoxic ratio by possibly inhibiting the indole-2,3-dioxygenase induction of the kynurenine pathway.
RESUMO
OBJECTIVE: To examine the psychiatric comorbidity in benign brain tumours. METHOD: A retrospective (5 years) data analysis at our 500 bed teaching hospital. The diagnoses of benign brain tumours were based on the record of final diagnoses in the case records confirmed by either CT or MRI scans. Case records of patients with clearly documented history of psychiatric symptoms of several weeks to several months duration were identified only if such symptoms had antedated a diagnosis of the brain tumour. Using a specially designed proforma, two psychiatrists rated the symptoms together. We also collected data on age, gender and CT/MRI findings. Consensus was reached on all cases in regard to the psychiatric phenomenology. The symptoms were divided according to their presentation into purely neurological or psychiatric symptoms. RESULTS: A total of 79 patients were identified as having a primary diagnosis of benign brain tumour. There were 56 female patients and 23 male patients. Seventy-two of these had meningiomas. Fifteen (21%) of 72 meningioma cases, eight men and seven women, presented with psychiatric symptoms in the absence of neurological symptoms. Affective disorders were a common presentation. There was no correlation between brain laterality and the psychiatric comorbidity. CONCLUSIONS: Psychiatric symptoms may be the only initial manifestations of meningiomas of the brain in a significant number of cases occurring in the fifth decade of life. Such patients must be investigated by brain imaging studies even if there are no neurological signs or symptoms.

OBJECTIVE: To review controlled studies of long-term treatment and their side-effects with newer dual action antidepressants following an acute episode of major depression. METHOD: A literature review (MedLine) was undertaken and references were selected for their relevance and methodology in describing their contribution to the examination of our objective. RESULT AND CONCLUSION: Three dual action antidepressants are identified: venlafaxine, mirtazapine and milnacipran. These are more effective and better tolerated than the older tricyclic antidepressants in the treatment of an acute episode of depression and in the prevention of relapse. They also offer advantages in that they lack autonomic side-effects of the tricyclics. However, sedation, nausea and sexual side-effects may occur with venlafaxine, and weight gain with mirtazapine.
